QUIC solves a lot of problems we have to solve manually (and were doing so) with TCP. Since the Net is expected to move more and more in favour of QUIC, UDP allowance is bound to see a surge if not already.
Well if Google will use it it’s already going to be ubiquitous

Some of the rest of the benefits are already covered in the article I think.
